Hey people i had a 300zx up for sale but not going to sell it atm. ALL HELP IS APPRECIATED. anywayz something happened when i start my car up it squeels now ive found out its from the alternator belt but i got mechanic to change belt but next day it squeeked again but mate said when i turn lights on and the cars on or i put aircon on it squeeks in the day even when the cars warm so i would like to know what use people think the problem is as use own 300zx's other people said could be the pulley not aligned properlly or belt needs to be lubed or could be a leak somewhere dont know to go or where to look to fix this annoying problem. DeZ.
How bad is the noise? I get a reasonably low db squeak with the headlights on that annoys the hell out of me!!! I hadn't thought about a pully out of line, but I'm not sure if that would be it, wouldh't that cause the pulley to 'wabble' (lack of brief decriptions ) rather than running consistantly offline? I'm interested to hear suggestions for this too.
I'd also recommend checking that both rubber radiator pipes are properly clamped onto their aluminium hardpipes, as leaks from these will drop onto your belts and may cause slippage. Also do as K-Zed says and re-tension the belt yourself so that you know it's tight.
Agree with Rob, Belt is almost certainly not tight enough. This is done from underneath with the car (on jack stands). Easy job. Cheers, Peter
cheers guys wow this was very quick it just happens mostly in mornings for about 20 secs or so till thermo kicks off than the high squeeling pitch will turn off but in the night its horror i think my neighbours are going to shoot me in the night time when the lights are on every set of lights i completly stop at will send my car or something to squeek its quiet embaressing seeing im driving a nice car not a $1,000 S*** box you know what i mean but people have given me suggestions like i said alternator pulley needs to be adjusted or tightened also put some kind of grip liquid on the belt to stop it squeeking or something leaking on the belt ! i love my car but it makes me embaressed in the night time that i have to drive with my windows up and roof on and system cranking lol so when people look at me i think what are they looking at are they hearing something im not :$ please help me fix this problems people would be much appreciated. Also i only paid the mechanic $40 to change the belts from old to new one
In the first 100 thou km service for my car I changed out all the belts for new ones. I followed the recommendations for tensioning the belts from the manual by using a spring gauge, a strip of metal and a ruler, and after it was done the belts never made a wrong sound for the next 100,000km. The next 100 thou km service I got lazy and just guessed the tightness of the belts (lost my spring gauge and remember throwing out the metal strip in my last move). Well I then had the belts squealing at me all the time for a month till I finally got under there and readjusted them, but once again I just guessed and got the same result just not as bad :stupid: So I got under there again and really tightened them up, and now they only squeal every now and again:rolleyes2: Moral of the story is that tensioning the belts correctly is a bit of a pain in the arse, but so are squealing belts :thumbup: My precious thumbs up is back and we have new emoticons!. Im so happy!:zlove:
Yeah... and who asked mods for the thumbs up smiley HAHA... Does sound Increase with rpm? Have you checked the bearings within the idler pulleys and within the alternator itself? I had a similar problem last week and got it fixed, all up it cost under 10 bucks for a new idler pulley bearing. Belt tension would be the first point of inspection, but if that doesnt fix the problem, look at your bearings :thumbup:
hey guys lol ill have to ask my neighbour i think it just needs to be retentioned unless theres a leak i cant c as the engine bay so squeezy but ye ive noticed why it doesnt sweak in day and thats because lol the lights or aircon aint on because if i turn the lights or aircon on it makes the car squeek or the alternator belt lol my lifes so embaressing now any more things it might be people got monday and tuesday off so got to do something lol " YES I KNOW UGLY DAYS TO HAVE OFF" Carsales man job
